Research Progress of MRI Diffusion Tensor Imaging in the Diagnosis and Grading of Brain Glioma

Brain glioma is a prevalent neoplasm within the central nervous system. Due to its highly invasive growth pattern, it is often indistinct from normal brain tissue, which complicates accurate diagnosis and grading of the tumour. Diffusion tensor imaging (DTI) is a method of microscopically monitoring the dispersion movement of water molecules. It can conduct both qualitative and quantitative analysis, reflecting pathological changes to the microstructure of brain tissue and non-invasively revealing white matter fibre bundles. This article reviews the research progress in the diagnosis and classification of glioma by means of quantitative study parameters and white matter fiber bundle display by diffusion tensor imaging.
